The ruling, which gives the state 60 days to act, comes as Gov. Ron DeSantis plans to convert a prison in North Florida into a second immigrant detention site.

U.S. District Judge Kathleen Williams' injunction formalized a temporary halt she had ordered two weeks ago as witnesses continued to testify in a multiday hearing to determine whether construction should end until the ultimate resolution of the case.

A federal judge ruled that the Trump administration must halt construction and stop bringing new detainees to Florida's "Alligator Alcatraz."
